Best Offer Module

[mac]

Can someone make this best offer module for use in ACTINIC?
For actal example see:
http://www.make-a-store.com/cgi-bin/demo1/category/700

you can haggle the price.

You could probably do this with some PHP / Javascript ..... you could set a user defined minimum bid level and test the input >= minimum bid

I am sure. But I need to have someone do it for me for $$$$$.
I am not a PHP expert.
can anyone do it for a fee?
